Kernel panic after upgrade

I did a base install from an Arch 0.7.2 CD. The system came up fine afterwards. I proceeded to do a pacman -Syu system upgrade. After rebooting, I get the following error:

kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

I'm doing this on a ThinkPad T60p (SATA hard disk).

What is the problem and what can I do to solve it?

On a side note: when a command is actively being run, such as a pacman upgrade, I'm able to move the caret/cursor around the terminal, including up onto previous lines. I've not got gdm running or anything, and I've not seen this happening on any of the other distributions that I've used. Is this normal, and what's causing this?

Re: Kernel panic after upgrade

Be sure you answered "yes" to the upgrade questions asked when doing the ....Syu....  In addition, if using lilo, you must modify lilo.conf for the mkinitcpio changes.  If using grub, changes are also necessary there AFAIK.

If possible, read the wiki for the details.

Thanks for that; I'd not adjusted my grub configuration.

Re: Kernel panic after upgrade

check our grub menu.lst and make sure the line

initrd /boot/something.img reads initrd /boot/kernel26.img

I had to do that when I upgraded and I had the exact same error you did,
